Search Help

To find information about a topic, simply type in a few keywords.  The more detailed your query, the more relevant your results.

Our search engine also comes with some advanced capabilities to help you find exactly what  you're looking for. These capabilities are best shown with a few examples:

Translated: require  CGI, require scripting        Finds "CGI Scripting", "CGI scripting", and "scripting of type CGI". Does not find the lowercase "cgi scripting", nor the abbreviated "CGI script". Translated: forbid CGI,  require scripts        Finds "Perl scripts", "Hollywood scripts", and lowercase "cgi scripts". Does not find "CGI definitions" nor "CGI scripts". Translated: prefer CGI, require scripts        Finds "Perl scripts", "CGI scripts", and "CGI Scripts". Documents with both terms appear higher in the list. Translated: require the  phrase "CGI scripts"        Finds "CGI scripts". Does not find "CGI Scripts" nor "scripts of type CGI". Translated: require  cgi (case insensitive), require words starting with "script"        Finds "CGI scripts", "cgi scripting", "Cgi scripter". The asterisk is a  wildcard representing any four or fewer characters. Translated: require Venus (case sensitive), require pictures,  forbid planet, prefer images        First lists "pictures and images of Venus", then "Venus pictures". Does not list lowercase "venus picture", nor forbidden "picture of planet Venus". Translated: ignores common words like where, is, and the - requires words containing "frog"        Finds "frog", "frogleg", and "bullfrog". To suppress the ignore feature,  use quotes, as in "Where is the *frog*?".

Note on  case sensitivity - only words or phrases containing an upper case character will  be treated as case sensitive. A search on "usa" will match "Usa", "USA", and "usA", while the term "USA" matches only its uppercase version.

The asterisk is a powerful search tool, but has some limitations. It cannot span words - that is, the query  "powerfu*earch" would not match the first sentence of this paragraph - and it can represent at most four letters or numbers. To avoid overly broad searches,  the asterisk can only be used in words or phrases which have at least three alpha-numeric characters. A search for "th*" would be ignored.
